IP Routing Parameters

[A], [A], [E], [G]

Some changes to IP Static Routes and IP Interfaces (described earlier) require an extra step to update the SmartSwitch 1800 software. Changing certain parameters will generate the message: Dynamic Routing Parameters

have changed. ............. Do you wish to update them at this time Y/N (N)? This

must be done, but if you are making several changes to IP Interfaces and Static Routes, you can save time by specifying N for each change until the final one. Entering Y after the final change will update all changes made to both IP Interfaces and Static Routes.

If you forget to specify Y after the last change, you can still update the FRM via On-line Update Dynamic Routing Parameters, [G] at the IP/LLC2/BRIDGE/IPX Interfaces Configuration menu (or

from the Main Menu).

Table 14-5 IP Routing Parameters

Parameter	Valid Values	Default Value


Router	valid IP address	255. 255.255. 255

Metric Count	1–255	1

Route Type	Network, Host, Default	Network

Route Destination	valid IP address or 0	0. 0.0.0

Destination Mask	valid IP address	255. 255.255. 255

Rou ter

is the IP address of a router that can reach the route destination.

Metric Count

is the number of "hops" (network gateways in the overall path over the internet) from the source to the destination.

Route Type:

Network defines a route for a network.

Host defines a route for a specific host.

Default defines a route that will be used if no other route is found.

Route Destination

is the IP address of the destination for host routes.

Destination Mask

is the mask used for network routes. It is used only during routing, to identify the portion of the address associated with the network.

When an IP datagram is received, the software "masks" off this portion of the overall address and searches for a match to the remaining address in the node's IP routing table. If there is no match, then the destination mask is checked. If no match is found here either, the default route (if configured) will be used. If the default route is not con- figured, the datagram will be discarded, and an error message will be sent to the source.

1800 specifications

Cabletron Systems, a leading player in network management and telecommunications solutions during the late 20th century, introduced several innovative products that played a crucial role in shaping enterprise networking. Among these were the Cabletron FRX6000, FRX4000, and the FRX1800, which delivered advanced features aimed at enhancing network performance, security, and scalability.

The Cabletron FRX6000 was designed as a robust multi-layer switch, ideal for large-scale enterprise environments. It supported extensive routing capabilities, allowing organizations to manage traffic efficiently even under heavy loads. The FRX6000 boasted high throughput rates and low latency, making it suitable for demanding applications. With support for various network protocols, including IP, IPX, and AppleTalk, its adaptability made it a versatile choice for diverse networking needs. Moreover, security features like VLAN support and Access Control Lists (ACLs) provided enhanced protection against potential threats.

Moving to the FRX4000, this model offered a balance between performance and cost-effectiveness. The FRX4000 maintained many of the essential features of its larger counterpart while catering to medium-sized enterprises. It provided Layer 3 routing and could handle multiple simultaneous connections, ensuring seamless communication across departments. The modular design allowed for easy upgrades, enabling businesses to expand their network infrastructure without significant overhauls. This made the FRX4000 an attractive option for organizations looking to optimize their network investments.

Lastly, the FRX1800, designed for small to medium businesses, focused on simplicity and ease of use while still incorporating powerful network management capabilities. Its user-friendly interface made it accessible for organizations lacking extensive IT resources. The FRX1800 provided essential functionalities such as Integrated Layer 2 switching and routing, network monitoring, and basic security features, ensuring that even smaller companies could maintain efficient, reliable networking without overwhelming complexity.

All three models utilized advanced technologies, including a high bandwidth backbone and state-of-the-art switching architecture, to enable fast and reliable data transfer. They also supported Quality of Service (QoS) mechanisms, allowing businesses to prioritize critical applications and ensure consistent performance across the network.

In summary, the Cabletron FRX6000, FRX4000, and FRX1800 were pivotal in enhancing network capabilities, providing organizations with scalable, secure, and high-performance options tailored to their specific needs.
